摘　　要：通过柴油机转速、车辆行驶速度、驱动力、扭矩及油门齿杆位置关联关系研究,提出一种装车条件下柴油机扭矩获取的技术方法,并根据使用环境条件进行扭矩标定。重点解决了装车条件下,由于柴油机扭矩测取困难,无法对动力性、经济性准确识别的问题。其结论对柴油机性能状态监测及状态评估有着重要意义。This paper put forward a method of acquiring torque under the real driving status through studying the relationship of engine speed,vehicle speed,driving force and throttle position.This method solves the problems such as：the difficulty of monitoring torque causes the power and economics performances identification may not be carried out accurately under the real driving status.The results have significant sense to monitoring and evaluating performance status of the diesel engine.
